Clearing an alarm

Clearing Alarms

When an alarm occurs, the screen title bar blinks red and an alarm 
window appears.

When an alarm occurs:

1.  Clear the alarm. Alarms can be cleared in two ways:

•  Locally at the controller by pressing OK (check).
•  Remotely through pin 6 (Error Reset) of the I/O 1 (input / output) 

connector. Refer to “Input / Output Port Pin Descriptions” on 
page 53 to connect inputs / outputs.

2.  If needed, correct the problem that caused the alarm. Refer to 

“Troubleshooting” on page 49 for complete troubleshooting 
information, including a list of all system alarms, causes, and 
corrective actions.
